smallest spy camera

Wireless spy camera glasses are powered by batteries. These batteries, however, are different from the type we often buy for our portable radios. They are so long-lasting they can keep the hidden video camera running for long periods of time. This feature of spy camera glasses is important. After all, anyone who's ever done any surveillance work can tell you your worst enemy is time. There's no telling how long you'd have to wait for your quarry to emerge from the office, for example, or head for his paramour's house.
